Figs 3A–E

Holotype: IRAN: ♀ West Azerbaijan Province, Mahabad, Sahoolan , 36˚39’19.80"N, 45˚56’46.23"E, 1–16 Aug. 2019, 1780, m. a. s., Malaise trap, A. Ameri leg. ( HMIM).

Paratypes: IRAN: 1♀, 4♂♂, same data and original depository as the holotype .

Type depositories: One female paratype is stored in NHRS. The holotype and remaining paratypes are stored in HMIM.

Etymology: The name refers to the collector of the type series, Ali Ameri.

Diagnosis: Enicospilus amerii Johansson sp. nov. ( Fig. 3A ) is similar to Enicospilus kokujevi Viktorov, 1957 , but has stouter, more numerous flagellomeres, the occipital carina dorsally flattened and the central alar sclerites of different shape. It also resembles Enicospilus cerebrator Aubert, 1966 (type in NHML examined), but has more elongate flagellomeres. The face in E. cerebrator is more evenly testaceous or yellowish, while it is white with a central brownish stripe in E. amerii sp. nov. Very similar also to Enicospilus opacitor Aubert & Shaumar, 1978 (type in NHML examined), but E. opacitor has a distinct gap between the lateral ocelli and the compound eye, evenly curved occipital carina dorsally, the proximal and central sclerites closer to each other and narrowly pale inner orbits. Notably Enicospilus opacitor , known from Israel, Egypt and Morocco ( Yu et al. 2016), is most likely the specimen depicted as Enicospilus sp. 1 in Gadallah et al. (2017).

Description: Fore wing length 13–14 mm. Body length 14–15 mm. Number of flagellomeres 58–61. Mandible strongly twisted with upper tooth about two × as long as lower tooth. First flagellomere slender, about 4.5–5.0 × as long as apically wide. Mid- and preapical flagellomeres about 1.8 × as long as wide ( Fig. 3C ). Temples strongly narrowed, in lateral view about 0.3 × the width of compound eye in both sexes ( Fig. 3E ). Lateral ocelli touching inner margin of compound eye. Clypeus apically truncate ( Fig. 3B ), moderately convex, in lateral view almost right angled. Mesopleuron closely punctate with transverse striae almost all over the entire surface. Epicnemial carina ventrally complete, sinuate. Mesoscutum with notauli weakly indicated anteriorly, closely punctate centrally, punctures becoming weaker and scarcer laterally. Scutellum with lateral carinae, its surface with dense, partly rugulose punctures. Proximal sclerite entirely pigmented, approximately triangular with rounded anterior angle, central sclerite semi-circular, pigmented distally, fading to unpigmented proximally. Distal sclerite weak and elongate ( Fig. 3D ). Propodeum with anterior transverse carina strong, anterior of the carina polished wihout punctures, posterior to the carina entirely reticulate-rugulose often with faint longitudinal striae centrally. Hind femur narrow, about 8.0 × longer than wide. Hind claws pectinate throughout their entire length.

Colouration: Uniformly testaceous ( Fig. 3A ). Inner and outer orbits widely pale. Mandibular teeth black. Ovipositor sheath testaceous, concolourous with the metasomal segments. Forewing veins and pterostigma testaceous.
